WILLIAM SMITH, OF SAN FRANCISCO, CALIFORNIA.

WATER-CLOSET..

SPECIFICATION 4forming part of Letters Patent No. 314,617, dated March 31, 1.885.

Application filed February 21, 1883.

To all whom it may concern:

Be it known that I, WILLIAM SMITH, a citizen of the United States, residing at San Francisco, in the county of San Francisco and State of California, have invented certain new and useful Improvements in Water Closets, of which the following is aspeciication.

My invention relates to improvements in water-closets in which a supply of water for flushing purposes is automatically admitted to the receiving-chambers and trap-pipes immediately connected with the basin or bowl and forming part ofthe closet.

In the drawings hereunto annexed, and which form a part of this specification, Figure l is a perspective view of a water-closet embodying my improvements. Fig. 2 is a vertical sectional view through the basin, plug-chamber, trap, and waste-pipe. Fig. 3 is an elevation showing more clearly the position of the siphon-trap. Fig. 4 is a vertical section showing the mechanism for automatically supplying the closet with iiushing-water. Fig. 5 is a longitudinal section through the rose or spreader. Fig. 6 is a side view, and Fig. 7 is a bottom view, of the same.

Similar letters of reference are used to designate like parts throughout the several views.

This closet consists of a basin and two communicating chambers or water-reservoirs, all placed together as compactly as possible. Within the larger one of these two chambers, and which I designate the Iloat-channbei"7 A, I place a weighted iloat, B, connected by ashort stem to the lever-arm C of a supply-valve. The short arm of this lever is pivoted to the vertical stemD of asupply-valve that is placed at the outer end of a trough, E, that extends from and forms part of the float-chamber A. This valve consists Aof a shell, F, having a flange, G, by which the valve-shell is attached to the under side of the trough, as shown in Fig. 4, the upper end of the shell being eX- tended within the trough and fitted with a plug, H, through which the valve-stem D is passed. The lower end of this valve-stem is provided with a head or disk that forms the lower thrust-bearing for a coiled spring, M, the upper end of which bears against the under side of the plug H. The valve-seat is made with a sharp narrow ridge, N, upon (No model.)

which the face of the valve is pressed by the action of the spring M, and the valve thus kept closed (when the basinis full)against the pressure of water coming from the supplypipe O.

A discharge-opening, P, is made-in the side of the valve-case, just above the seat N, and to this opening is connected a pipe, Q, that leads to the basin or bowl R. The end ot' this pipe Q is provided with a rose or spreader, S,-the head of which is hollowed out, as shown atT in Fig. 5, and pierced upon either side witha hole, U. The under side of the spreader is cleft or provided with aslit, V, extending upwardly and ontwardly'and reaching to the holes U U.

As the water issues through the spreader a portion of it will be forced through the side holes, U, and directed around the basin, just below the top rim thereof, and meeting midway will fall down upon thefloor of the basin.l That portion of the stream issuing from the slit V will likewise be deflected around the bowl and also straight downward, thus thoroughl y washing every part of the basin.

The outlet from the basin to the waste-pipe is controlled by a plug, W, operating within the plug-chamber X, and composed oi'a piece of perforated casting provided with a liftinghandle, Y, and having a rubber facing, Z, upon its lower face, which, when the wastepassage is closed, rests on a solid cast-brass seat, A', placed within the plug-chamber immediately below its junction with the basin. The plug is made of a less diameter than that of the chamber within which it is placed, in order that a free passage may be had around it for the water in the basin to enter thc short pipe B', which communicates with the iioatchamber above the line of the plugs valveseat A', as shown in Fig. 2.

Immediately below the valve-seat A', I attach a trap-pipe, C', extending upward to near the top of the closet, and having an air-dome, D', placed at its upper'bend. From the airdome said pipe is carried down toapoint considerably below its union with the waste-pipe, and is connected with the base of' the iioatchamber, and thus a perfect trap is formed which eiectually prevents the passage of sewer-gas into the float-chamber, while the IOO ' the service-pipe,and the water has escaped,

the weight of t-he lioat will cause it to rest near the bottom ofthe containing-chamber, thus depressing the long arm of the valve-lever to which it is connected, and thereby open the passage for the water to the basin. Vhen the plug W has been returned to its seat, it will prevent the waterfrom iiowing from the basin directly to the wastepi pe, and will cause it to iow through the short pipe B into the lioat-chamber, gradually raising the ioat, and likewise filling the long arm of the trap-pipe G. W'hen the float has been raised suiiiciently high, the valve will close, as hereinbefore described, and the supply of water be cut off. However, should the valve fail to operate from any cause, the surplus water will liow over the top bend of the trappipe and flow down the short'arm and out into the waste-pipe, and no damage will occur to the premises.

After the closet has been used, the plug W is to be raised from its seat until it clears the opening from the bowl to thewastefpipe E, when the body of water in the bowl will rush out into and down the Waste-pipe, the current being augmented'by the water contained within the plug-chamber, float-chamber, and trappipe. rlhe falling of the float will then open the supply-valve, and the process of fillingthe closet will then be repeated.

The top of the plug-charnber is closed by a tightly-fitting cap, G, having a central open ing through which the lifting-stein of the plug passes. The rubber facing to the plug is of a diameter slightly less than the bore of the chamber, and by this construction the water contained within the said plug-chamber is prevented from being lifted out at the top, and is permitted to flow down between the plug and sides of the chamber.

It will also be seen that by reason of the long arm of the trap-pipe entering the floatehamber on a line below that at which the short arm enters the waste-pipe that all danger of the said pipe siphoning itself is prevented, as the seal of the overflow is below the plug NV, and is not due to the retention of the said plug upon its seat, and abody of water will be always contained within the float-chamber and long arm of the trap below the dotted line Z Z. (Shown in Fig. 2.)

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

l. In a water closet operating automatically, having a basin, R, and waste-pipe E, the combination, with the chambers A and X, conneeted by a passage, B', of the trapped pipe C', substantially as andfor the purpose set forth and specified.

2. In a water-closet, the combination ofthe bowl R, having waste-pipe E, the chambers A. X, one of which is provided with a plug, WV, for closing the outlet of the waste-pipe, and the other with a iioatingball, B, connected with a self-closingsupply-eock that discharges into the bowl, the pipe B, and the trapped pipe C', having dome D, substantially as shown and described.

3. In a water-closet, the combination, with the bowl R, of the rose S, having a hollow head, T, provided with side openings, U U, connected by an undercut slit, V, substantially as shown and described.

In testimony that I claim the foregoing I have hereunto set my hand and seal.
